COIN CONTROLLED MECHANISM Application filed May 7,

10 provide a more eflicient and compact mechanism for receiving and utilizing the coin to operate the coin driving member, than was contemplated for use in connection with the Ca sler apparatus, which required a great deal of space to properly house it.

My invention consists briefly, in the use in connection with a coin driving member adapted to impart a broadside arcuate movement to a coin, of a swinging coin actuated 20 member having a simple link and bell crank connection with the means for releasing a so called tripping rod.

I accomplish the objects of my invention by means of the simplified coin controlled 25 mechanism hereinafter described and set forth in the appended claims, and illustratively exemplified in the accompanying drawings, in which, Figure 1 is a side elevational View of a mutoscope showing the wall broken away to disclose the coin controlling mechanism; Figure 2 is a similar View on an enlarged scale of just the coin actuated member and the link and bell crank connection therefor; and Figure 3 is a substantially vertical sectional view taken on lines 33 of Figure 1.

Referring to the drawings, denotes the casing in which the entire mechanism of the mutoscope is housed. One side of the device comprises a removable panel or door 11 for the purpose of giving access to the interior of the housing when replacement of the picture reel 12 is desired. The mechanism for driving the reel 12 as well as the release and lock of the tripping rod 13 is all well known, as disclosed in the said Casler patent, and it will suffice to state in this connection that while the tripping rod 13 is of the same shape and performs the same functions as the tripping member in the pat- Serial No. 361,115.

ent, it is important to note that, because of the simplified coin controlling mechanism embodied in the present invention, the tripping rod is a great deal shorter in length than it has been practical to use heretofore in apparatus of this character. I further drive my coin controlling parts directly from the crank shaft 1 1, which carries the crank 15 at the front and outside of the casing 10 in the usual manner, and which between the oscillating shaft connection 16 and the front wall of the casing 10, carries a cam 17 having a gradual rise to the high point and then a radial drop to its hub, as illustrated in Figure 8. The shaft 14 on opposite sides of the cam 17 is journalled in bearings 18 which form an integral part of a frame plate 19. While the frame 19 carries substantially all of the mechanism of the device, and is known to be triangularly shaped, it is with a lateral extension 20 projecting from upper end of the front side of the triangle that I am concerned in connection with the present invention. The ex tension 20 is virtually a depending plate arranged directly over the crank shaft and cam 17 and forms one side wall for the coin slot. Integral with the plate 20 and projecting rearwardly thereof at the lower end is a pair of cars 21 accommodating a shaft 22 therebetween upon which a coin actuated plate 23 is pivotally mounted. A coiled spring 2 1 wound about the shaft 22 is tensioned with one end engaged against a boss 25 on the plate 20 between the ears 21 and with the other end engaged against the coin actuated plate 23 yieldably urging it towards the plate 20. The lower free end of the plate 28 is provided with a slot 26 to permit the passage of the cam 17 there through when no coin has been inserted. The inner side of the coin actuated plate 23 at its hinged end beyond the inner and lower end of the plate 20 is provided wit-h a boss 27 from which a pin 28 projects to receive the lower end of a link 29, the upper end being pivoted on one arm of a bell crank lever 30. The lever 30 is pivotally mounted on the frame 19 and the free end of its other arm abuts the forward end of the tripping rod 13. It will be clear that rearward movement of the coin actuated plate 23 will draw downwardly on the link 29, rock the bell crank lever 30 and push the tripping rod 13 towards the rear of the casing 10 to release the picture reel 12.

It has been stated that the plate 20 forms one wall of the coin slot, the other walls therefor are formed by a hinged plate 31 pivotally hung from shaft 32 projecting between two spaced ears 33 which are an integral part of the plate 20 and project from its forward face adjacent the upper end. The hinged plate 31 comprises a flat front wall with side walls 34 projecting towards the plate 20 and enclosing a passage which projects from a slot 26 in the front wall of the casing to a point substantially below the lower end of the plate 20. The lower free end of the hinged plate 31 is provided with a slot 35 which registers with the slot 26 in the plate 23 and which permits the passage of the cam 17 therethrough. The free end of the hinged plate 31 is further provided with side projections to aid in guiding a coin after being forced by the cam to depress the plate 23. A coiled spring 37 on the shaft 32 tends to normally urge the plate 31 into position against the fixed plate 20. A coin A placed in a coin receiver 38 disposed over the slot 26 and on the front of the casing 10, follows a downward path between the plates 20 and 31 and is stopped by a pair of lugs 39 which are integral with the lower end of the hinged plate 31 on opposite sides of the slot 35, and which in the closed position of the coin actuated plate 23, project just under the lower free end of the latter. The coin A in this position is supported on the lugs 39 between the two plates, and bridges the space between opposite sides of the slots 26 and 35.

In the operation of the machine after a coin has been inserted, as just described, the crank handle is rotated in a clock wise direction bringing the radial side of the cam 17 into contact with the face of the coin A where the latter fills in the space between the walls of the slots 26 and 35. Continued movement of the cam 17 forces the coin rearwardly and with it the plate 23 until the relative positions of the latter and cam 17 allows the coin to slip from the face of the plate 23 and fall into a coin drawer through a chute 40. It will be clear of course that the rearward rocking movement of the coin actuated plate 23 has imparted the necessary movements to the link 29 and bell crank lever 30 to project the tripping rod 13, which result it is the object of this invention to accomplish.

Having now described my invention and its manner of operation what I claim and desire to secure by Letters Patent is:

1. In a coin controlled mechanism for a consecutive view apparatus, a picture carrier,

a crank shaft for actuating the carrier, a tripping rod for locking said picture carrier, a coin driving member on said shaft, a coin actuated member having an opening in the path of movement of said driving member, means actuated by movement of the coin actuated member for projecting said tripping rod to release the picture carrier, and means for guiding and supporting a coin over said opening in the coin actuated member, whereby the latter is operated by movement of the coin driving member against the coin.

2. In a coin controlled mechanism for a consecutive view apparatus, a picture carrier, a crank shaft for actuating the picture carrier, a tripping rod for locking said picture carrier, a coin driving member on said shaft, a coin guide having a passagedisposed in the path of'the coin'driving member, comprising a plate to guide and support the coin over the said passage and in the path of the driving member, a coin actuated member against which the coin is supported in its position over the passage, and connecting means between the coin actuated member and the tripping rod, whereby movement of the former is transmitted to project the latter.

3. A coin controlled mechanism, comprising a rotary coin driving member, a hinged guide, and holder for a coin, said guide having a slot in one end disposed in the path of movement of the driving member, a coin actuated hinged plate normally held against said guide and having a slot in its end registering with the first slot, and means operated by movement of the coin actuated plate when a coin is supported by the holder across the slots and engaged by the driving member to control the operation of the apparatus, said coin driving member comprises a cam having a radially disposed side adapted to pass through the first slot and abut a coin to swing the coin actuated plate, and a crank shaft upon whichthe cam is mounted.

4. A coin controlled mechanism, comprising an upright fixed plate forming one side of a coin slot, a coin actuated plate slotted at its lower end and hinged to the lower end of said fixed plate and yield ably held in alinement therewith, a cover plate hinged at its upper end to the fixed plate to form the opposite side of the coin slot, said cover plate having side walls contacting with the fixed plate to form the other two sides of the coin slot, the cover plate being slotted at its lower end to register with the first slot and having two projections, one on each side of the slot projecting beneath the coin actuated plate to support a coin between the plates and over the slots, and'a rotary coin driving member movable through said slots' when no coin is present and abutting the same when one is inserted to swing the coin actuated plate for controlling the operation of other mechamsm.

5. A coin controlled mechanism, as claimed in claim 4, including a link connection from the coin actuated plate, and a bell crank lever for the link connection for transmitting angular movement of the coin actuated plate in one direction to an angular movement of the bell crank lever at right angles thereto.
